Audio Service Mode revisited
Remember this:
Get into the NAV diagnostics mode (covered in these forums before) - hold the Climate and Audio controls while switching the parking lights on and off 3 or 4 times. This must be done immediately after tuning the key on. The new step is:
• Once the diagnostics auto test completes, press the menu key on the touch screen, then hold the AM button for 5 second until it beeps.
• The display will now show “Audio”
• The TAPE button toggles through F, R and W for Front, Rear and Woofer. The UP DOWN button can set these from 0 to -80 dBs.
• The FM button toggles between P1, P2 and L, where P1 and P2 are equalizer frequency settings and L is the overall level from 0 to -20 dBs. I haven’t figure out what the equalizer setting do exactly.[/I]• The setting appears to be non volatile so switching the ignition off keeps the values. I now have a system that is much closer to my preferences with the controls flat – always a good place to be. Happy tweaking.
This has been reposted by several members over the years. I was trying this out recently and a piece of info missing from the above post is: what the P1, P2, and L controls actually do. I have tried several different combos but they don't seem to change the sound on my system at all.
Also, where is the amp located in our cars (1998) and are there any manual settings to be made on it? Thanks.

Your amp is under the front passenger seat - same amp as in the standard Pioneer system. There are no adjustments on the amp.
Like other obscure information, how the equalizer works is probably explained at https://techinfo.toyota.com
Do an internet search (e.g. Google) and you will find generic information on what equalizers do.
